7 Claims.

, My invention relates to railway vehicles, and particularly to animproved vehicle body construction.

An object of my invention is to provide an improved railway vehicle bodyconstruction.

Another object of my invention is to provide an improved railway vehiclebody frame construotion.

Further objects and advantages of my invention will become apparent andmy invention will be better understood from the following descriptionreferring to the accompanying drawings, and the features of noveltywhich characterize my invention will be pointed out with particularityin the claims annexed to and forming part of this specification.

In the drawings, Fig. 1 is a side elevational view of a locomotiveembodying my improved body and frame construction, partly broken away toillustrate the arrangement of the frame at the back end thereof; Fig. 2is a plan view of the locomotive shown in Fig. 1, partly broken awayadjacent the back end thereof to show the body construction at this end;Fig. 3 is an enlarged side elevational View, partly broken away, ofsections of the locomotive frame shown in Fig. 1 illustrating therelative arrangement of the frame construction at the front and at theback ends of the locomotive; Fig. 4 is an enlarged partial sectionalplan view of the locomotive frame shown in Fig, 2, taken along line 44of Fig. 3 and partly broken away to show the relative arrangement of thelocomotive body and frame construction at the front and back ends of thelocomotive; Fig. 5 is an elevational sectional view taken along 5-5 ofFig. 4; and Fig. 6 is a sectional end elevational View taken along line6-6 of Fig. 3.

Referring to the drawings, I have shown a railway locomotive which isadapted to be supported on'a pair of main driving trucks Hl providedwith driving wheels II and provided with guiding and trailing trucks [2and I3 arranged respectively at the front and back ends of thelocomotive. These trucks are arranged to support the locomotivesuperstructure which comprises a plurality of compartments arrangedto'house the locomotive power and control equipment and the fuel supply.

In many modern high speed locomotives, it has been found desirable toprovide heat transfer devices such as radiators or condensers forcooling engine cooling water or exhaust steam, and it is necessary toprovide an arrangement which will 55 supply an adequate ventilatingmedium circulation to remove the heat from these heat-transfer devices.I have found it desirable and advantageous to arrange the heat-transferdevices adjacent an outer surface of the locomotive and to provide asupporting frame for the locomotive 5 superstructure which will notinterfere with the proper cooling and operation of these heat-transferdevices. In order to support the outer locomotive wall surface of thefront portion of the locomotive, I provide a plurality of load-support-10 ing truss elements adjacent each side thereof, including upwardlyextending posts l4 connected together by diagonally extending braceelements l5 which are secured to the posts M by gusset plates l6 and H.The upper and. lower ends of the posts 14 and the braces I5 also aresecured together by longitudinally extending beams l8 which also arereinforced by being securely welded to the gusset plates l6 and [1- Inorder toprovide a more rigid transverse frame construction, 20-

I arrange transversely extending beams Id between the truss elements onopposite sides of the locomotive and securely weld these beams Hi to theside frame load-carrying truss elements. The lower portion of the framealso is rigidly secured 25 together by a plurality of transverselyextending angle beams 20 over which floor plates 2! are arranged. Thefloor plates 2| form the upper surface of an air distributing duct whichis closed I on its lower side by lower plates 22 secured to 30 the underside of the transversely extending beams 20. A plurality of theload-carrying trusses is arranged adjacent each side of the locomotivefor a given length thereof extending from the front end of thelocomotive substantially to the 35 point at which the heat-transferdevices are to be arranged. These truss elements are arranged insubstantially parallel aligned relationship longitudinally of thevehicle and outer wall plates 23 are secured thereto to provide an outerwall sur- 4O face for the vehicle. A roof structure 24 also is securedto the upper transversely extending beams I9 in order to provide asuitable cover for the 10- comotive equipment. I

In the illustrated construction, the heat eX- 45 change device isarranged adjacent the back end of the locomotive, and it has been founddesirable to arrangelouvers 25 to regulate the flowof air into thesedevices. These louvers 25 are arranged substantially in alignment withthe outer 50 wall 23 at the forward part of the locomotive and ittherefore is desirable to arrange a supporting truss frame as in theforward end offset from these louvers. Such a frame is arranged spacedinwardly from the louvers, and includes a plurality of load-carryingtruss elements comprising upwardly extending posts 26 secured togetherby diagonally extending brace elements 27 and a longitudinally extendingbeam 28 secured to the upper ends of the posts 26 and to the diagonallyextending braces 27. A plurality of these loadcarrying truss elements isarranged along each side of the vehicle spaced inwardly from the trusselements at the front end of the vehicle, so as to provide atransversely offset frame, which is substantially parallel to the frameat the forward end of the locomotive. The upper ends of the trusselements on opposite sides of the vehicle are secured together bytransversely extending angle irons 29 and the lower ends of the trusselements on opposite sides of the locomotive are rigidly securedtogether by transversely extending channel beams 30. Floor plates it arearranged over the channel beams 30 and are securely welded thereto. Theouter wall surface at the back end of the locomotive is formed by upperand lower plates 11.2 and 33 and by the upwardly extending. louverelements 25. This outer vehicle surface is, therefore, arranged intransversely spaced relation with respect to the truss elements at theback end of the locomotive and provides a compartment therebetween inwhich the heat-transfer devices may be arranged. I provide reinforcingsupporting plates 34 which extend between the posts 26 and the outerwall plate 32 to provide an arrangement for supporting the upper end ofthe louvers 25. In has an rangement, the truss elements adjacent theheattransfer devices extend substantially from the back end of thelocomotive for a predetermined length thereof to a point substantiallyopposite the end of the truss elements which form the longitudinallyextending frame in the front portion of the locomotive. In transferringforces from one frame to the other of this offset truss construction, itis necessary to carry both tension and compression at the top and bottomconnection, as well as shearing forces therebetween. In order to balancethe moments of forces at the connection between the frames of each pair,I provide a triangulated cross truss construction including shear plates35 extending transversely between the two frames of each pair at theiradjacent ends and cross trusses or brace elements 36 and 37 at the topand bottom of the frames. These triangulating cross trusses 35 and 3!extend between the second post M from the end of the frame section atthe front por-, tion and the first post 25 of the frame section at theback portion of the locomotive and from this post 2S to the channelmember l9 extending between the second post E4 on each side of thelocomotive, respectively, to provide a rigid interconnectedload-carrying unitary frame structure,

While I have illustrated and described a particular embodiment of myinvention, modificaions thereof will occur to those skilled in the art.

I desire it to be understood, therefore, that my invention is not to belimited to the particular arrangement disclosed, and I intend in theappended claims to cover all modifications which do not depart from thespirit and scope of my invention.
